Application of CO2 Laser Marking Machine for Cloth and Leather

Laser technology is also widely used in the footwear and leather industries. The advantage of laser is that it can quickly engrave and hollow out various patterns on various leather fabrics, and it is flexible in operation without any deformation of the leather surface, so as to reflect the color and texture of the leather itself. That is to say, the CO2 laser marking machine. It also has many advantages such as high engraving precision, hollow without burrs, arbitrary shape selection, etc. It is suitable for the needs of processing manufacturers such as shoe uppers, shoe materials, leather goods, handbags, luggage, and leather clothing. Laser engraving refers to the operation method of connecting the laser equipment to the laser engraving software and entering the artwork into automatic engraving. At present, laser engraving is a mature technology in the field of laser processing and has a wide range of applications. Using this technique, any complex figure can be engraved. Hollow engraving and non-penetrating blind groove engraving can be carried out, so as to engrave various patterns with different shades, textures, layers and transition color effects. With these advantages, laser engraving caters to new trends in garment processing.

Laser cutting of appliqués There are two important steps in computerized embroidery process, namely cutting before appliqué and cutting of blanking material after embroidery. In the traditional processing technology, the disadvantage of the knife mold processing method used for cutting before embroidery is that it is easy to produce fabric fringes, and the processing accuracy is limited by the knife mold. Restricted the development of appliqué embroidery. However, after embroidery cutting, most of them use hot cutting processing, which has the disadvantages of large cutting edge gap, yellowing and hard edges, and difficulty in alignment. Heterosexual graphics rely on manual hand cutting, which is easy to loose edges and produce waste products. Therefore, there is an urgent need for an advanced processing method to replace these two old processing methods. Although laser processing is also a thermal processing method, due to the high focus of the laser, the irradiation spot is small, and the thermal diffusion area is small, so it is very suitable for cutting textile fiber fabrics. The specific performance is in a wide range of processed fabrics, smooth incision without flash, automatic closing, no deformation, graphics can be freely designed and output by computer, no need for die and so on. This makes laser processing an industry-recognized alternative. Laser marking has the characteristics of high marking accuracy, high speed and clear marking, and can print various characters, symbols and patterns on the plane, curved surface and flying objects of hard, soft and brittle products. Laser marking is compatible with various advantages of laser cutting and engraving. It can be precisely processed on metal and organic polymer sheets, and complex patterns with small size can be processed. The printing mark has the anti-counterfeiting performance of non-wear, and can be specially made for cloth labels, leather labels, metal labels, various logos and LOGOs with complex and fine printing patterns. It is the choice for brand clothing and apparel processing. For a long time, there has been an alignment problem with the cut edge of the logo, the cut edge of the embroidery pattern, and the perforated parquet in the embroidery pattern. The existing automatic visual tracking cutting system is a big step forward on the basis of traditional manual alignment and cutting, and can automatically position and cut by sub-aligning points. However, the random deformation of textile products cannot be automatically corrected, so a large amount of waste products will be generated. At present, some companies in the industry have successfully developed an automatic identification edge finding cutting system, which can automatically generate a cutting path according to the edge of the woven logo graphic, and accurately use the laser to cut along the edge. It can also automatically position and cut and punch the patterns in the embroidery graphics, which fundamentally solves the problem of alignment.

How the laser works may not be clear. The following laser editors will take you to analyze the application of lasers:

CO2 lasers are commonly used molecular gas lasers, and are also widely used industrially in gas lasers. CO2 lasers use a mixture of CO2, N2 and He. for working substances. Laser transitions occur between two vibrational-rotational energy levels in the electronic ground state of the CO2 molecule. The role of N2 is to improve the excitation efficiency of the upper energy level of the laser, and He contributes to the evacuation of the lower energy level of the laser. The CO2 laser emits invisible laser light with wavelengths of 10.6um and 9.6um. The laser can work either continuously or in pulses. Its output power and energy are large, and its high efficiency can reach 15%~25%. The continuous output power of its commercial devices can reach the order of 10,000 watts. CO2 laser has been widely used in drilling, cutting, welding and heat treatment in industry, and it is an ideal laser in industrial applications.

Like other molecular lasers, the working principle of CO2 lasers, that is, the stimulated emission process is also complicated. Molecules have three different motions: 1. The movement of electrons in the molecule, and its motion determines the electronic energy state of the molecule; 2. The principle vibration in the molecule, that is, the atoms in the molecule constantly vibrate periodically around its equilibrium position - it determines The vibrational energy state of the molecule is determined; the rotation of the molecule, that is, the molecule rotates continuously in space as a whole, and this motion of the molecule determines the rotational energy state of the molecule; the CO2 molecule is a linearly symmetric molecule, and the two oxygen atoms are respectively in the carbon atom. on both sides. The atoms of the molecule are always in motion, constantly vibrating away from their equilibrium positions. According to the molecular vibration theory,
